This is the shocking moment a riverside home collapsed as floodwaters eroded the riverbank in northern Thailand.

Video shows the empty house tipping over into a swollen river in Chiang Mai province on Tuesday afternoon.

River levels rose after heavy rains, sending a deluge sweeping through two sub-districts in the province.

Residential areas and farmlands were left swamped while knee-deep waters rendered roads impassable to small vehicles.

Local authorities dispatched rescue teams to evacuate stranded villagers.

The Thai Meteorological Department said a monsoon trough was stretching across northern Thailand, bringing isolated heavy rains.

Residents were advised to beware of heavy rains that may trigger flash floods in low-lying areas.
